We got a late start Sunday and by the time we walked to the Circo Massimo market, got the stuff we planned to cook for lunch, and were most of the way back, we were too hungry to wait two hours. Emma was nearby, open, and could seat us outside, so we gave it a try.
The selection of bottled beers is exceptional, the one Menabrea pilsener on tap was decent, much better than the old stalwart Peroni.
Bruschetta with Datteri tomatoes was excellent. Some Americans would complain that it was oversalted.
Supplí al telefono was crunchy and tasty but would have been better if it had been fried to order (was only lukewarm). My companion's fritto misto was good but Nuvolari's was better and cheaper.
My SuperBio pizza (margherita with all organic ingredients) was delicious but could maybe have stayed in the oven a few seconds longer, it was a bit blonde. Still haven't made it to Baffetto to check if that's still the one to beat.
"Tiramisù espresso" was not a traditional tiramisù but rather a hot espresso poured over some sponge and topped with a complicated cream. Really delicious, barely sweet.
My companion's cheesecake was very good, a little creamier than the usual cakey style they do here. The berries that came with it were exceptional.
With a big bottle of Pellegrino, total was €61.50, a bit steep for what it was but I appreciate having a good pizzeria open at lunchtime.
UPDATE: Here's a report on a second visit where I was more impressed with the pizzas and overall.
